I'm going to try linking to a site with a lot of interesting information about this age-old herb. This newbie blogger doesn't quite know where to put these links yet, so patience may be needed here. I think that maybe they go over to the right hand side of the page ? If I can't get it right I'll post the info next time...
Long used in Ayurvedic medicine, it seems some of the claims about it's ability to improve memory, and restore lost cognitive skills, reduce anxiety - and a lot more besides, have now been substantiated by scientific studies.
It appears that effects are noticed after about 8-12 weeks of taking the herb, either fresh, or as a supplement. The desired dose is about 30g fresh herb per.day.
It really does look beautiful in a water pot, even if you never use it for it's claimed benefits.
